Switch zoning for RamSan storage systems
Switch zoning configurations for the RamSan® system include considerations for fabric zoning, target port sharing, host splitting, and controller splitting.
Fabric zoning
To enable multipathing, ensure that you have multiple zones or multiple RamSan and Storwize® V3500 ports for each zone when you are zoning a RamSan system to the Storwize V3500 back-end ports.
Target port sharing
The RamSan system can support LUN masking to enable multiple servers to access separate LUNs through a common controller port. There are no issues with mixing workloads or server types in this setup. LUN Masking is a licensed feature of the RamSan system.
Host splitting
There are no issues with host splitting on a RamSan system.
Controller splitting
RamSan system LUNs that are mapped to the Storwize V3500 clustered system cannot be mapped to other hosts. LUNs that are not presented to the Storwize V3500 can be mapped to other hosts.
